I've deployed my API to an Azure App Service and get the error:
The resource you are looking for has been removed,had its name changed,or is temporarily unavailable.
any time I try to hit the endpoint of the only current operation in the API. All of the files have deployed correctly in the wwwroot folder and if I enter url/filename where url is the base url and filename is any of the files in the folder, I am able to download the file. The API works when run locally, hitting the operation returns the expected json result.
Running a trace gives the rather generic result:
System.NullReferenceException 2 Object reference not set to an instance of an object. Stack Trace 1 mscorlib!System.Diagnostics.Tracing.EventSource.SendCommand mscorlib!System.Diagnostics.Tracing.EventSource+OverideEventProvider.OnControllerCommand mscorlib!System.Diagnostics.Tracing.EventProvider.EtwEnableCallBack mscorlib!dynamicClass.IL_STUB_ReversePInvoke
The routes are configured correctly (in that it works locally) - the error implies that a related file is missing, however checking the folder in Kudu shows the files match the contents of the bin folder. Any ideas on what is going wrong here? Or how to determine what the missing resource is? Thanks for reading.
